Super Hurricane .24 Engine

[Chancey Chorney]

Hi there. I had recently acquired this engine in a 'lot' purchase. Overall condition is very well, minus the missing parts. I had originally bought it as it looked neat, then thought that there may be someone out there that would have better use or need for such an engine. I do not know much at all about these things, other than it appears to have good compression. So, in short, I was wondering if there may be any interest in acquiring this engine by anyone out here that collects such old things like this. If so, please PM me and we could work on something. Thank you.

The Canadian-built Hurricane .24 was never very popular.  Being a rotary valve, it is somewhat stronger than the Ohlsson .23, but much less than its contemporary K&B Torpedo 24 or 29.  It is not prized as a collectable engine.

Yours is missing the ignition points, indicating possibly having been run on glo plug.  You will find that a replacement ignition point set would cost about the same as this engine's value, complete with ignition, and ready to run.

Yes, I would believe so. I do know that the head is tapped for a standard glow plug. I may have a needle assembly to fit as well. The main thing missing otherwise would be the backplate behind the propeller. Seems doable to make. If so, I just may try to run the darn thing. After all, that's what it was meant for, right? Thanks for the info.

My 1952 AeroModeller Annual includes a synopsis of an engine test article for the "Hot Top" (i.e glowplug) Super Hurricane.  One thing of note was the manufacturer's recommended fuel mix: 1 to 2 parts nitropropane, 5 parts SAE70 oil and 13 parts gasoline!  (The test, however, was conducted on ordinary Mercury No 5 glow fuel, so there was no indication of how the engine would have performed on such a weird brew.  On the Mercury No 5, it turned a respectable - for 1952 - .279 b.h.p. at 11,600 rpm.)

Chancey.  The standard 1/4" glo plug, and the same size spark plug, have the same threads.  1/4-32. 

I would certainly recommend the more common glo fuel mix.  Not more than 10% nitro, and lots of lube: Try for 25% oil, which can be a mix of castor oil and synthetic.
